I deally you want to have the sipohn (Main) pipe a 1/4 inch lower then the other two to make it so that it will start first or you can put the open up by 1/4 over the others and leave the siphon and emergency at the same height.

gary - no, not - you - I meant ME as the "un-intenede hijacker" HAHA!!
autodave: what scott said above is correct - just to add one thing to that: drill all the holes at the sme height, and add 1/4'' -3/8'' of vertical height to the plumbing of the other two fittings. Can be done by cutting a piece of pipe 1/4'' longer that adds height. If this is not clear - let me know.

atodave:
2 things ultimately determine the height of water in the overflow:
1. The height of the opening to the main and durso style/open channel drains
2. The ball valves on your main and open channel.
You can adjust the water height up or down to a large degree witht eh ball valves. My system is approx. 1'' of drop from the tank - which creates no noise.

question, can this be modified to an external overflow to come out the bottom, just by putting the elbows in the over flow? if that makes sense. I just ordered my tank with this in mind but just realized I have the holes i nthe bottom of the over flow. If I have it go through with the vents in the actual over flow with the elbows set up similarly will this work?

thats what I want to do but I only have a 3 inch over flow and was intending to do them sideways over a 60 inch coast to coast verses your back to front set up. will this still work?

Hey Folks... I finally got my tank filled with water and started running it tonight... it is quiet! The only sound I hear at the moment (and I don't have much running on it yet) is the trickle of water going over a chamber in my sump). I have a few little problems to work out (i.e., final adjustments with the elbows in the overflow, a bulkhead leak that's really small, etc.), but otherwise just wanted to say THANKS for all the help here (it's been awhile back that I had all my questions). It's late now, so no pics tonight... hopefully I can get them up here tomorrow.
